While I was hanging out near the hotel where I was staying on a business trip, I found a girl who I was sure would be aroused by instinct, something that happens once in 10 years! She agreed to watch me masturbate for the first time in her life, saying it was just to watch. When I asked a married woman with a female announcer face to watch me masturbate, her breathing got faster and faster, and her flushed face showed her anticipation for an erotic development. The wife, with her eyes glazed over and wanting it, entered erotic mode. Her mouth was half-open as if she wanted it, and she seemed to be desperately trying to control herself from impulsively giving me a blowjob. After witnessing the sperm that was shot out, the wife's libido limiter was removed and she was completely aroused. The dam of libido that had been teased by watching me masturbate completely collapsed, and she became a wife who wanted a dick herself.
